| 摘 要： | 本文以理想流体的势流理论为基础，建立高速双体船的模型，由于双体船每一片体长宽比Ｌ／Ｂ很大，兴波接近于线性理论，计算时在船体表面及自由表面布置Ｒａｎｋｉｎｅ源，采用线性自由表面条件，对片体方尾后自由表面作特殊边界处理，从理论上预报了高速双体船在不同Ｆｒｏｕｄｅ数，不同片体间距船宽比时，船体周围的流场分布，船体内、外侧表面的波形、压力分布以及兴波阻力系数。

| Abstract: | Based on the potential theory of ideal fluid,this paper gives a type of mathematical model of high-speed catamaran.Because of the value of L/B for demihull of catamaran is very large,the authors introduce linear free surface condition, deal with the special free surface downstream transom stern to calculate the velocity distribution in the flow field, pressure distribution on the hull surface,wave profiles and wavemaking resistance coefficient at different Froude numbers.different gaps between the twin demihulls. |
